Shunyata Research Theta USB Cable

The Theta is the second USB cable in Shunyata’s range, it is the direct replacement for the popular Delta and it offers a superb level of performance and represents great value for money, it is priced at £500 for a 1.5m length, it costs £60 to add increments of 25cm to the length of the cable.

Theta Series signal and digital cable products feature continuous-cast Ohno copper. Ohno copper is an ultra-pure conductor drawn using heated moulds that cast the wire into a singular crystalline structure. The Ohno conductors used in the Theta Series are then extruded with a fluorocarbon dielectric and custom-shielding elements using Shunyata Research’s exclusive PMZ (Precision Matched Impedance) process. This extrusion method tightens the tolerances of the conductor surface, dielectric and the precision placement of the shield. To achieve these finely drawn tolerances, the extrusion and braiding machines must be run at one-quarter normal speed during the manufacturing process.

Theta speaker cables and power cords feature VTX™ (hollow core) and VTX-Ag™ (pure silver center) conductors, both with an outer layer of ultra-pure OFE copper for enhanced performance. Finally, all Theta cables are conditioned for 4-days using Shunyata Research’s advanced Kinetic Phase Inversion ProcessTM (KPIPv2TM), which conditions conductor metals at a molecular level. Theta Series cables are terminated with Shunyata’s custom-designed connectors and cold-soldered terminals. These custom-designed attributes elevate Theta Series performance far beyond expectation, regardless of cost.
